GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 223,407, dated January6, 1880.

' Application filed March 24,1879.

To all whom it may concern Be it known that I, DANIEL STE NK, of Janesville, in the county of Rock and State of Wisconsin, have inventedcertain Improvements in Grain-Binders, which are fully described in thefollowing specification, reference being had to the accompanyingdrawings, in which Figure 1 represents an end elevation of a binderembodying my improvements; Fig. 2, i a front elevation of the same; Fig.3, a detail section, on an enlarged scale, taken on the line X X, Fig. 2Fig. 4, a detached view of the point of the binding-arm on an enlargedscale; Fig. 5, a section taken on the line Y Y, Fig. 4; Fig. 6, an endelevation, showing the devices used in operating the band-holders; Fig.7, a detail view of the pinion and pin which operate the cam-lever;Fig.8, a plan section of the twisting and cutting devices on an enlargedscale; Fig. 9, a similar view with the cutting mechanism and bladeremoved; Fig. 10, a bottom view of the twister; Fig. 11, a detached Viewof the cutter.

My invention relates to that class of automatic grain-binders in which avibrating binding-arm is used, and in which the binding material iswire.

It will be understood, of course, that the 0' binding apparatus is to beattached to a grainharvesting machine; but, as the attachment may bemade in any well-known way, and my improvements are confined to thebinding apparatus alone, I have not shown the harvesting-machine.

It consists in special devices and combinations of devices, all of whichwill be hereinafter fully "described, and will be more definitelypointed out in the claims.

Some of the main features of the binder here shown have been fullydescribed and shown in a prior case of mine, and hence will be onlyalluded to in the present description.

In the drawings, A represents the grain-receiver, which is provided witha suitable slot to accommodate the movements of the binding-arm and thecompressor.

A suitable frame, B, is provided for the mounting and support of theoperative parts of the binding mechanism, the upper part, b,

of which frame projects outward over the receiver, and rock-shaft O ismounted on this upper portion of the frame, to the inner end of whichshaft is attached the binding-arm D. This binding-arm is preferablyjointed-that 5 5 is, made of two parts pivoted together, as in my formercase, though my other improvements may be used with a stiff arm as well.

The rook-shaft O is oscillated by means substantially the same as in myformer invention, and, as before, the head portion of the hinding-arm isprovided with a heel'extension, d, which projects back over the othersection of the arm.

A guard, D, is also attached to the upper side of the head-section ofthe binding-arm. This guard is of metal, in the form of a bow, and itsends are attached, respectively, to each end of the section. It may alsobe used with a stiff binding-arm, in which case it'would be attached toeach end of thearm.

The second rock-shaft, E, is also mounted on the upper part of theframe, and is provided at its inner end with a bent crank, e, the outerend of which is connected by a link, E, with the heel-extension d of thebinding-arm. At the other end of the rock-shaft E is the crankarm 0.

On the back portion of the upright frameis provided a cam-lever, F, theouter end of So which is connected to the crank-arm e by a pivoted rodor link, f. The lever F is of triangular shape, and in its body is cut acam, f.

The gear-wheel G, mounted on the same portion of the frame, and whichoscillates the 8 shaft 0 by means of a crank'pin and connectin g-rod, isalso provided on itsinner face with pin g, which is arranged to movewithin the cam-opening f, thereby vibrating the lever F on its pivot,which is located at the inner upper corner thereof. The parts are allarranged so that this lever will be raised just as the binding-armstarts upon its upward or return movement, thereby oscillating the shaftE, and by means of the crank c and link turn- 5 ing upward and backwardthe heel-extension d, which vibrates the outer section of thehinding-arm on its pivot, and s0 turns the bindinghead that it is liftedfrom thewire, and moves back on a path above and in front of the pathfollowed on its downward stroke. Just as the binding-arm reaches itsupward limit the same devices operate to straighten it out, so that itis ready for the downward stroke, and at this point there should beproper provision for a rest of the arm, if it is necessary.

The shaft H, mounted on the upper portion of the frame, carries upon itsinner end a starwheel, I, mounted loosely thereon, and attached theretoby a coil-spring, i, and pins 'i,

so that the wheel will yield on its shaft to pressure in one direction,but is held by a stop from movement in the other direction.

On the shaft H is a fixed notched disk, It, and by the side of it alarger disk, 11., mounted loosely on the shaft, and provided with aspring-pawl, 7L2, arranged to engage with the notches in the disk h. Theloose disk h is also connected by a link, h with the crankarm h on therock-shaft O, and the parts are so constructed and arranged that whenshaft 0 is turned to raise the binding-arm the shaft H is rotated farenough to bring one of the compressing-arms down just a little beyondthe twister, as shown in Fig. l of the drawings, in which position it islocked by means of a fixed notched disk, J, on the shaft andspring-detentj. Here it is firmly held during the downward vibration ofthe binding-arm, the bundle being compressed between said arm and thearm of the wheel standing in front thereof, and in the movement of theshaft 0 to throw the binding-arm downward the disk It will be turnedback on the shaft H, the spring-pawl slipping over the disk h intoposition to engage with another notch thereon upon the reverse movementof the shaft 0.

The wheel I is provided with three arms, though, of course, more may beused, if necessary, and it will be seen that it is a rotary yieldingcompressor, intermittent in its movements, and each arm operatingsuccessively. It will also be seen that upon each forward movement ofthis compressor the descending arm will also act as a bundle-discharger,pushing the bundle before it from the receivenso that each arm performstwo funetionsfirst, to discharge the bundle as it comes into place, and,secondly, in its fixed position to act as a yielding compressor for thenew bundle as it is gathered down.

The mechanism above described for rotating the compressor maybe changedfor some other devices, and perhaps a more simple mechanism will bedesirable. For instance, the shaft may be geared to the main gearing ofthe binder, so as to be moved intermittently by it, and to be locked inposition in the same manner as the binding-arm and twisting mechanism.

The twister K is provided with slots on each side thereof, as shown inFigs. 9 and 10 of the drawings. It is also provided with hooks 7c,projecting outward from each side of the twister, and extending aroundacross the openings into the slots, for the purpose of gathering thestrands of the band. It is also provided, as usual, with a gear-pinion,k by means of which it is rotated by a gear-wheel, L, on the upper endof an upright shaft, 1, which carries a bevel-pinion, l, on its lowerend. This pinion meshes with a similar pinion, m, on a horizontal shaft,m, which carries on its outer end the driving-gear M, which is rotatedat the proper intervals by a gearsection on the main driving-gear of thebinder. Just below the twister are two toothed wireholding pinions, Nand N, mounted on horizontal shafts a n, the former of which extendsthrough the upright portion of the frame, and carries upon its outer enda toothed or ratchet wheel, M, as shown in Fig. 6 of the drawings.

lhe pinions N N are for the purpose of holding the wire, which is caughtand crimped between the teeth of the pinions, and the refuse portion fedout from between the same in a well-known way. They are givenv anintermittent rotation by means of a dog or pawl, O, which is pivoted tothe lower inner corner of the lever F, and is caused to engage with theteeth of the ratchet-wheel n by a spring, 0, the parts being arranged sothat when the lever is thrown downward, thereby pushing the inner lowercorner backward, the ratchet-wheel will be turned a certain distance.

The ratchet-wheel is also provided with a spring pawl or detent, 0,which is arranged to engage with the teeth and prevent the wheel fromrotating backward.

The cutting-blade P is pivoted to the plate over the twister, and has anenlarged extension back of its pivot, in which a cam-opening, p, is cut.The upper end of the shaft Z projects through this opening, and isprovided with a crank-pin, p, which is driven around within the opening,and thereby vibrates the cutter-blade at the proper time to cut thewires.

The end of the baud-wire being held between the pinions N N, themovement of the into one of the slots on one side of the twister andmakes a first strand of the band. As the rotation of the twisterproceeds the other hook gathers the second strand of wire which has beenbrought down by the binding-head, and this strand is carried into theslot on the opposite side of the twister from the first, the movement ofthe twister being given at the proper time for completing the twist inthe band. The twister may, however, take the first wire before therising of the binder-arm, and then take the second wire on thecommencement of its movement to form a new twist.

It will be understood from this description that the two strands of theband to be twisted are gathered into separate slots on opposite sides ofthe twister, and are then twisted together, a twist being formed bothabove and below the twister. The cutter is vibrated just as the twist isformed, and before the twister stops, and severs first one wire and thenthe other, as eachis brought against it, in its position with the bladeextending somewhat over the twister.

The band-holding pinions are rotated about as the binding-arm is tocommence its downward movement, and the twist below the twister is drawndown betweenthe pinions, from which it is shed out continuously, andserves to insure the proper retention of the band. The band is broughtto the twister by the binding-arm in the manner heretofore shown by me,and the bindinghead is provided with a recess on its inner side toaccommodate the rotation of the twister, as in my former application.

It will be understood, also, that when the jointed arm is used thebinding-head will be lifted from the wire and carried up on its backwardstroke above the grain, so as not to interfere therewith by themechanism described above.

As already stated, the guard on the binding-arm and the arms of therotating compressor are so arranged relatively that the end of thecompressor-arm, which moves down ward as the binding-arm moves upward,is within the path of the guard on the arm, so that the compressor-armwill not interfere with the grain, which will be held back by the guard.This guard also operates to hold back the incoming grain, which may bedelivered while the band is being twisted and the arm is on itsdownstroke. The parts must, of course, be timed so that theoperationsherein described will take place at the proper intervals; butthis is a matter which is well understood, and the particular mechanismfor accomplishing this result, in all respects, it is not necessary todescribe here.

The devices for holding and adjusting the band and regulating itstension are the same as shown in my prior invention, and therefore willnot be described here. I do not confine myself to the precise form andarrangement of all the parts herein described, as it is evident that11161'6 mechanical changes may be made without departing from theessential features of construction and operation which are peculiar tomy improvement.

I am aware that, broadly, a jointed bindingarm is not new, and that thespecial motion given to the jointed binding-arm is, in some respects,similar to that heretofore shown in harvester-rakes.

I do not here claim, broadly, the combination of a jointed binding-armand mechanism for controlling the movements of said arm, and compellingits outer section to pursue different tracks or paths in its downwardand upward vibrations, as this improvement constitutes thesubject-matter of claims in an ap plication of mine of prior date.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A jointed binding-arm, D, fixed on the .vibrating shaft 0, incombination with the rock-shaft E, provided with the crank e and thelink E, whereby said binding-arm is caused to move over the platform inits upward movement and through the platform in the downward,substantially as and for the purpose set forth.

2. The lever F, provided with the cam-opening f, in combination with thewheel G, provided with the pin g, the connecting-rod f, rock-shaft E,and rock-shaft 0, connected to the wheel G, whereby the binding-arn1 isvibrated up and down and flexed on its joint at the same time,substantially as described.

3. The rotating star-wheel I, attached to the shaft by yieldingconnection, to operate as an elastic compressonagainst which the bundleis compressed by the bindingarm, substantially as described.

4:. The rotating compressor, in combination with the bindingarm and aguard, D, arranged relatively, so that the compressorarm, in itsdownward movement, will be within the path of the guard on its upwardmovement, substantially as and for the purpose set forth.

5. The rotating compressor I, the shaft H, to which it is attached by anelastic connec-. tion, so as to yield thereon, and mechanism whereby anintermittent rotary motion is transmitted to said shaft, and stoppingmechanism for locking it at the proper intervals, in combination with avibrating binder-arm mounted on a separate shaft, substantially asdescribed.
